Abstract: PURPOSE:To fix a thickness of stacked fins by expanding tubes while laying the fins at proper positions with a presser mechanism for the fins of servomotors and a force-up mechanism to force up the fins with so weak a force that curl height parts are not deformed. CONSTITUTION:A push plate 36 to receive the fins on the side of tube bends of a cross line type heat exchanger 101, a pressure mechanism 38 to energize this push plate 36 to the fin side and a fin presser driving device 12 having a position detecting means are provided.

Since positioning suitable to each heat exchanger is carried out by an external controlling means using the servomotors 14a, 14b for the driving device, fin positions to the tubes are controlled before expanding the tubes and the energizing force to the fins is set under a deforming strength of the curl height part, a steady tube expansion can be performed. In this way, the accuracy of positioning dy the servomotors is improved, a plurality of conditions is stored in a memory and the time for changing a preparation can be brought nearly to naught.

Abstract: PURPOSE:To determine the specification of a virtual computer identifier independently of the capacity of an I/O device by arranging plural identifiers and a registration table for the upper and lower addresses of storage areas corresponding to the identifiers in the I/O device. CONSTITUTION:An instruction 400 is inputted to an instruction execution control part 150, decoded by an instruction code and interpreted as a virtual computer identifier (VMID) registering instruction.

Title: Gas burner emitting flimy flame
Inventor: KONDO HIDESUKE
IPC: F23D14/74
Filed: 1990-04-10
Abstract: PURPOSE:To provide a gas burner for a filmy flame which prevents the fluctuation of a filmy flame and improves combustion efficiency by a method wherein an annular recessed part, an annular protrusion part, and a recessed stage part or a protrusion stage part are formed on a shield surface along the outer peripheral part of the filmy flame. CONSTITUTION:A jet flow 4 injected through an injection nozzle 12 produces a laminar flow state in which a velocity of flow is uniformized and stabilized as the jet flow is raised, and gradually horizontally dispersed as it is raised to increase the sectional area of a flow area. A velocity V of flow of the jet flow 4 in a vertical direction is gradually decreased and the stagnation point of a velocity V=0 of flow of the jet flow 4 is produced at an intersec tion between the central line of the jet flow 4 and a shield surface 31A. The jet flow 4 is deflected by means of a shield plate 3A and radially spread along the shield plate 3A. A shearing layer 43 by viscosity is formed at a boundary between the jet flow 4 and the open air and a boundary layer 44 is formed along the shield surface 31A. In the shearing layer 43, a turbulent flow C is always generated, the turbulence flow C exercises an influence of the outer peripheral part of the jet flow 4 to induce pulsation wherein the velocity of flow of the outer peripheral part is changed bit by bit. However, since a vortex D slightly changed by an annular recessed part 32A at intervals of a specified period is generated, turbulence of the jet flow 4 by the turbulent flow C can be prevented from occurring at a filmy flame forming area.
